H UB-CAP.

SPECIFICATION forming part of Letters Patent No. 551,290, d'atedDecember 10, 1895.

Application filed November 21, 1894. Serial No. 529,503. (No model.)

T at whom it may concern:

of the city of St. Louis, State of Missouri, have invented certain new and useful Improvemerits in a Combined Band and Cap forlVheel- Hubs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a combined band and cap for wheel-hubs; and it consists in certain novel features of construction that will be hereinafter described and claimed.

The object of my invention is to construct an improved combined band and cap for wheelhubs that when applied to the wheel-hub will present a neat and pleasing appearance, and also entirely exclude dust, sand, and other foreign substances that are injurious or detrimental to the working of the hub upon the axle.

In the drawings, Figure l is a side elevation of my invention. Fig. 2 is a vertical longitudinal sectional View thereof. Fig. 3 is an elevation of the inside of the dust-cap, of which I make use in carrying out my invention.

In the construction of the device as shown, 1 indicates a cylindrical thimble open at both ends, and which is adapted to be secured directly upon the outer end of the wheel-hub. On the exterior and the rear edge of this thimble 1 is formed an integral flange 2. Diametrically arranged on the inside of the thimble 1, and adjacent the edge opposite the one on which the flange 2 is formed, are integral ears 3, the same being provided with screwthreaded apertures 4.

corresponds to the thickness of the forward edge of the thimble 1.

Oppositely arranged and passing through the dust-cap are apertures 11, the same being countersunk and adapted to receive screws 12 when said cap is in position upon the thimble 1. Said screws 12 engage in the screwthreaded apertures 4 in the ears 3, as apertures 4 register with the apertures 11 when the dust-cap is properly arranged.

In the practical use of my invention, the thimble 1 is securely placed upon the outer end of the wheel-hub in the usual manner. The dust-cap 5 is then positioned upon the thimble 1, the edge of said thiinble engaging in the annular groove or depression in the edge of said dust-cap, and the apertures 11 in the dust-cap registering with the apertures 4 in the ears 3 that are formed integral with the thimble 1. Ordinary screws, such as 12, are now passed through the coinciding apertures, thus firmly and rigidly securing the dust-cap to the thimble 1.

By providing the flange 9 on the dust-cap and the annular groove or depression 10in which the edge of the thimble 1 is located, a perfectly dust and water proof joint is made.

When it is desired to gain access to the nut upon the end of the axle, the screws 12 are withdrawn from the apertures din the ears 3 and the dust-cap removed from its position upon the thimble. be plainly seen, is simple and expeditious.

Wheel-hubs provided with my combined band and cap present a very neat and pleasing appearance, the nuts upon the axle cannot possibly become disengaged and v lost, dust, sand, or water cannot enter between the hub and the axle from this end of the hub, and a combined band and cap thus formed and constructed possesses superior advantages in point of simplicity, durability, and general efliciency.

What I claim is- The improved band and cap for wheel-hubs, comprising the thimble 1 having an integral flange 2 on its rear edge, diametrically opposite integral ears 3 formed on the interior of said thimble adjacent the edge which is opposite the flange 2, said ears having screw-threaded This operation, as may IO Thimble, said dust-ca p having diametrically opposite countersunk apertures 1 l and screws 12 engaging said apertures and the threaded apertures at of the said ears, substantially as herein specified. 1

In testimony whereof I affix my signature T5 in presence of two Witnesses.
